About this tag
The Irp tag is associated with I/O Request Packet (IRP) memory allocations in Windows. On WindowsForum.com, users have reported serious memory leaks in the nonpaged pool traced to the Irp tag, causing system lockups and exhaustion of physical memory. These leaks have been observed on systems running Windows 7 Ultimate x64, particularly when hosting VirtualBox VMs. The poolmon tool identifies the Irp tag as the primary culprit, with nonpaged memory growing from typical levels to several gigabytes over days. Troubleshooting steps discussed include restoring the system to a prior state to rule out recent updates or driver changes. The tag covers discussions of diagnosing and resolving IRP-related memory leaks in Windows.

Windows 7 Serious memory leak in nonpaged pool (Irp tag)
I have a serious memory leak in nonpaged pool, which happen to be Irp packets. Here is the whole story. The system is Win7 Ultimate x64 which I primarily use to host some VirtualBox VMs. Around beginning of May I noticed that the box started to lock up and it was rock solid for almost a year...- Rafcio
